So pleased with these that we already ordered another set for backups.
Other then that perfect for 5amp per hour max 12volt usage.
These work great with the (HitLights 5-24V Easy Plug Dimmer for Single-Color LED Strip Light, 2A Max) Dimmer switch.
These work a bit differently then the female ones for the dimmer switch, you have to push them up into the plastic tubing for the dimmer. It does stretch the tubing for a full flush. While the female adapters work perfectly without problems.
Worked like a charm.
The screw down screws were a bit tricky to use as I was slipping in 22 gauge wire and had to fold the ends to make it thicker so the Screw can hold the wire down.
The screw when "screwed" pushes down a metal sheet inside that clips or bites the wire.
THere are + and - signs on top to indicate the HOT and neutral wire for insertion.
Bag came with 10 pcs, I have tried 2 and both worked fine.
i.e. often used for the ground station equipment running on 12V DC: remote video receivers, diversity equipment...
I find it particularly well adapted for that R/C usage as the length of the cables can vary quite a lot depending on the antennas position, and it's super fast to attach a cable to that connector.
I found the "+" marking to be connected to the center contact on the batch I received. As I wanted to make these center positive, that worked great.
In all cases, please check with a multi-meter to see what post connects to center, and what polarity your equipment requires. [measure twice, cut once would be more like measure twice, avoid smoking your electronic equipment).
For those that have never used anything like this if you use them in a high air moisture environment consider some outdoor electrical wrap or even a bit of dielectric grease on all connection points to prevent corrosion over time. NOTE: this is no fault of the product, just simple electrolysis that happens when power passes thru different metals exposed to moisture.
Save yourself the headache...if you're still running analog systems as new...and buy these, baluns, and Cat5 to run everything over a single cable.
